MEANS FOR ADMITTING AIR TO INTAKE-MANIFOLDS.

Application filed May 17, 1916.

. all whom it may concern:

Be it knownthat I, VVILLIAM C. ALTI-IEN, a citizen of the United States, residing at Columbus, in the county of Franklin and State of Ohio, have invented a certain new and useful Improvement in Means for Admitting Air to Intake-Manifolds, of which the following is a specification.

The object of this invention is to provide simplified and inexpensive means for admitting and controlling the admission of an auxiliary supply of air to the intake of an explosive engine whereby the gas mixture is better oxygenated and heavy particles broken up prior to its ignition. The finer the fuel division the more rapid and complete will be the explosion.

The invention is embodied in the construction herein shown and set forth, the feature of novelty being claimed at the close of the detailed description.

In the drawing Figure 1 illustrates in elevation the carbureter and a portion of the intake manifold of an ordinary gas engine of a motor vehicle, my invention being shown in connection with said manifold.

Fig. 2 is a sectional view on a larger scale on the line II-II Fig. 1.

Fig. 3 is an end view of the automatic valve.

Fig. 4 is a side view of the casing for containing the automatic valve.

Fig. 5 is a side view of the casing containing' the manipulated valve.

In the views designates the ordinary carbureter and 11 a fraction of the intake or manifold of an ordinary gasolene engine.

In applying my invention I tap or perforate the manifold at its neck above the junction of the carbureter therewith, and thread said perforation to receive the casing 13 of the automatic valve la. The casing 13 is threaded at its outer end and is there provicled with a slit or port 15. Threaded upon the outer end of the casing 13 is a cap 16. This cap 16 has an internally threaded neck 17 to receive one threaded end of a nipple 18, the other end of said nipple receiving the casing 19 of the manifold valve 20. The valve 20 works on a seat 18 in the end of the nipple. l/Vithin the casing 19 is a spring 21 tending to press said valve 20 onto its seat. The casing 19 is provided with air inlet openings 22 so that when the valve is 0E its Specification of Letters Patent.

seat the air has access to the slit and to the casing 13 and manifold when the automatic valve 14 is drawn 0H its seat.

The automatic valve 141 is a hollow cylindrical or cup-like structure and fits closely to reciprocate within the bore of the casing 13 and, at its headed end against the cap 16. The headed end of this valve is ported as shown at 23 and the valve works on a stem 2d threaded in the cap 16 which stem is therefore adjustable independently of the valve to compensate for loss of tension by reason of heat and use. Secured on the stem 24 is one end of a coil spring 25, the other end of which presses against the automatic valve and tends to hold its headed end against the cap 16 so as to close the ports therein. The pressure of the spring 25 can be changed or adjusted by turning the stem 24: in one direction or the other according to the degree of pressure desired. 26 is a 1' am nut for fixing the stem in position after adjustment.

The needle or manipulated valve 20 has a wire or cord 27 attached to it extending to a finger piece 28 working in a socket member 29 on the dash board 30 of the vehicle. The finger piece 28 can be pulled out and given a quarter turn to rest on the socket member in position to hold the valve 20 off its seat when air is to be admitted to the manifold.

In starting the engine, especially in cold weather, the valve 20 is left on its seat so as to exclude air because it is important that the explosive mixture be rich. After the engine has become warm the said valve 20 is withdrawn from its seat so as to admit air.

When the said manipulated valve 20 is off its seat the suction of the intake causes the automatic valve to move 0E its seat thereby permitting air from the casing of the manipulated valve to pass through the slit or port 15 of the automatic valve case", through the ports 23 of the automatic valve and to the manifold. The extent to which the automatic valve moves in its case on the slit or port 15 by reason of the suction of the intake stroke of the piston determines the quantity of air admitted to the intake.

The wire 27 can-be incased in a tube 31 to protect it from injury or accidental operation.

My invention can be cheaply attached to any internal combustion engine and the fuel ssi more thoroughly oxygenated and finely o divided. With theme of my invention the combustion is more complete, resulting in a saving of fueland a lessening of carbonization. o

l/Vhat I claim is: I o

l. l /leans for providing an auxiliary air supply to the fuel intake of an internal combustion engine comprising, in combination, a primary air inlet, a valve for controlling said primary air inlet, a cylindrical valve casing having a port in its side communicating With the primary air inlet, a valve sliding in said casing actuated by the suction of the intake to open said port, and a spring actuating said valve to close said port, said valve having an air inlet in its end through Which air is admitted to the intake When the aforesaid port is opened, and means for regulating said spring independently of the valve for controlling the primary air inlet.
